PT5M_USB1 contains all the qsi data obtained with pt5m between 2012-09-13 and 2013-06-26 and is now stored in the Sheffield USB-disk archive.

PT5M_USB2 contains all the qsi data obtained with pt5m between 2011-09-06 and 2012-09-10 and is now stored in the Sheffield USB-disk archive.

USB28 (1.5TB, tiny Toshiba) contains all the qsi data obtained
with pt5m between 2013-06-26 and 2015-01-14, the date we switched to
the Officina Stellare telescope. A backup of all of the python scripts and the
log files are also on this disk, taken on 2015-01-14. The disk is now
stored in the Sheffield USB-disk archive.

USB3 is in Vik's office and is used for ULTRACAM backups and storing reduced
ULTRACAM data.

USB10 died during the October 2007 WHT run - Maxtor replaced it and
this is now in the pt5m crates (I think!)

USB11 (750GB) is in the ULTRACAM crates and acting as a spare.

USB15 is lost! It was returned to Sheffield from
Warwick in March 2009 and seems to have disappeared.

USB29 (1.5TB, tiny Toshiba) was in the pt5m crate acting as a spare,
but I can't find it now! Seems to be lost.

USB33 (1.5TB, tiny Toshiba) also contains some backups -
silver_drpc_backup/ contains an rsync of the ULTRACAM1 (silver DRPC) with
the following directories: admin, cc, observer, rhickman, root, sl,
star, trm, ukatc, ultracam_data, vsd. Note that the ultracam_data/ directory
contains old backups from IMEDIA1, UCAM2 and UCAM3, plus another folder
(ultracam_data/root) with older backups of ULTRACAM1. This disk is now stored
in the Sheffield USB-disk archive.

USB36 is currently in the lab at Sheffield and needs to be re-used
for the ULTRASPEC+TNT runs in the 2018/19 season. (It currently
contains GTO+NARIT data from 13/10/2015 to 01/11/2017, all of which can
be safely deleted.)

USB38 (1.0TB, tiny Toshiba) is in the pt5m crate on La Palma
and awaiting connection to ron to use as the main archiving disk.

USB42 (2.0TB, tiny Western Digital) is currently connected to the
ULTRASPEC DRPC and contains the NARIT+GTO data from November 2017
onwards.

USB43 (2.0TB, tiny Western Digital) is currently connected to the
ULTRASPEC DRPC and contains the NARIT+GTO data from February 2018
onwards.

USB44-45 (2.0TB, tiny Western Digital) are in the ULTRASPEC crates
in Thailand for use in a future run there.

USB46 (2.0TB, tiny Western Digital) is with Tim (Somsawat) (or is
it now with Stu?) for temporarily storing his MOSCAM calibration
data. This will be reused in a future MOSCAM science run.

USB51 and USB52 (2.0TB, tiny Western Digital) are currently connected to the
ULTRACAM DRPC and will be used for the ULTRACAM+NTT runs in 2018.

USB53-54 (2.0TB, tiny Western Digital) are in the ULTRACAM crates
for use on the NTT in 2018-2020.

HIPERCAM_USB1 (2.0TB, Western Digital Elements, USB3) is now
permanently stored in the Sheffield lab and contains data from the
second HiPERCAM run on the GTC in April 2018 (14th-19th, but no data
on 19th due to poor weather). USB1 also contains a copy of the data
from the first HiPERCAM run on the WHT in October 2017 (17th-22nd) -
these data have been processed by Stu's script to correct the exposure
times in the FITS headers. The original, unaltered files have been
kept on this disk as well, in the directory orig_data/, but a bug in
Stu's script means a few of the exposure time headers are wrong: if
you want the uncorrupted orig_data/, use the copy on HIPERCAM_USB2.

HIPERCAM_USB2 (2.0TB, Western Digital Elements, USB3) is now
permanently stored in the Sheffield lab and contains data from the
first HiPERCAM run on the WHT in October 2017 (17th-22nd). The data on
USB2 have been processed by Stu's script to correct the exposure times
in the FITS headers. The original, unaltered files have been kept on
this disk as well, in the directory orig_data/.

HIPERCAM_USB3 (2.0TB, Western Digital Elements, USB3) is now
permanently stored in the Sheffield lab and contains data from the
first HiPERCAM run on the GTC in February 2018 (2,4,12-14th). The data
on USB3 have been copied to the archive at Sheffield (but not yet
Warwick?).

HIPERCAM_USB4 (2.0TB, Western Digital Elements, USB3) is still
connected to the DRPC at the GTC and will be used for the next GTC run
in April 2018.
